Researchers from Bayreuth University and Konstanz University are developing new methods to control ultra short laser emission using soliton physics and two pulse combs in a single laser. This method has the potential to greatly accelerate and simplify laser applications.Traditionally, the pulse interval of lasers is set by dividing each pulse into two pulses and delaying them at different, mechani...
A sketch of the imaging and holographic parts of a transient holographic microscope, including a pulse sequence, to illustrate the signal modulation method. By imaging the pinhole array at the sample position, a diffraction limited excitation spot array can be created, allowing for the simultaneous collection of transient data around 100 excitation spots.Femtosecond transient microscopy is an impo...
Quantum photonics is one of the important research directions in the quantum field, which utilizes the unique properties of light at the quantum level. The core of this field is the deterministic single photon source, which sequentially emits individual photons through spontaneous emission and is the cornerstone of quantum communication, computing, and secure encryption. However, under environment...
According to the Physicists' Network, scientists from Lawrence Livermore National Laboratory (LLNL) in the United States ingeniously combined the high-power laser emitted by the National Ignition Facility (NIF) with the ultra light metal foam to create the brightest X-ray ever. These ultra bright high-energy X-rays play an important role in many research fields, including imaging of extremely dens...
Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
